GAS-DISTRIBUTING 'MEGI-IAN ISM.

Specificatiofi of Letters Patent.

Application filed June 15, 1814:. Serial No. 845,226.

To all whom it may concern: .Be it known that I, DUDLEY E. MonnAY, a citizen of the United States, residing at Roanoke, in the county of Huntington and State of Indiana, have invented certainnew and useful Improvements in Gas-Distrlbuting Mechanism, of which the following is a specification.

The object of my invention is to provide a mechanism Which may be used to control the inlet and exhaust of a gas engine and which is so constructed that a. uniform efliciency of results is accomplished at all times.

A further object -1S tos9 construct the mechanism that a I for the intake and the exhaust and that this port will be opened at the proper time to; ad-

' mit the charge to the cylinder, will then 3-3 of Fig. 4. Fig.

be closed during the compression and firing and will be again opened to permit the exhaust of the burnt cycles of the engine ases. g Yet another object is to so construct the mechanism that the necessity for the use of separate valves to control the intake and the exhaust to the engine is obviated and the opening of the port for the intake and the exhaust is accomplished gradually, likewise the closing of the port at the end of each of these cycles.

With other objects in View, which will be referred to, my invention'consists in. the peculiar combination and novel arrangement of parts, such as will be hereinafter more fully described in connection with the accompanying drawings and more particir larly pointed out in the appended claims In the drawings:-Figure 1 is a View in vertical section through the upper end of the cylinder of a gas engine with my inven- Fig. 2 is a horizontal sectional view on the line 22 of Fig. 4. Fig. 3 is a vertical sectional view on the line 4 is a transverse vertical sectional view throughthe. case and the operating cylinder of the mechanism.

'lhe mechanism comprises the. case 1 which i is adapted to be connected with the cylinder 2 of the engine at a point over the inlet and exhaust portwhich -is positioned to 001m municate with the explosive chamber of the cylinder andin Fig. l is indicated by the dotted lines at 3, as extending through the single port may be used a better disc] osod cylinder head. This case 1 may be secured to the cylinder in any desired manner and apassage 4:- formed through the Wall thereof will establish communication with the opening or port 3 provided in the cylinder 2 to act as a common inlet and exhaust port. A gas-supply pipe 5 is secured in the opening v6 through the case 1 which opening is preferably located at a point diametrically op posite to the opening 4 and slightly offset therefrom in the direction of the longitudinal'extent of the case. A cylinder 7 is revolubly mounted within the case 1, a shaft 8 being connected with this revoluble cylin.

der and provided with a gear 9 to mesh With the gear 10 secured on the shaft 11 which may be turned by gear intermeshing with gear on the crank shaft or in any suitable manner to travel with and have its speed regulated by the speed of revolution of the crank shaft, the manner of making this connection will be perfectly obvious and is therefore not closure.

A gas duct 12 the cylinder 7 adjacent the o ening 6 and as stated, the opening 6 and the opening 4' are sooffset that theopening 4 has no normal communication with this gas duct 12. An arm or branch 13 is provided from the gas duct 12 to extend to a position that it revolves adjacent e opening 4 through the easel, and as SllQ'nll in Figs. 3 and 4, when this branch 13 is turned to a pdsition to cover the opening lcomn'iunication is established from the gas-supply pipe through the gas duct 12 and this branch to the interior of the engine cylinder 2.. A part of the wall of the cylin der 7 is out auay to form a passage at 14, which passage is in alinement with the bmnch l3 from-the gas duct 12 and is preferably placed just in advance thereof, as in Fig. 4. passage 1: in this relation, the engine is permitted to exhaust from the end of a firing cycle to the commencement of the intake cycle and the cylinder is thus scavenged of-all burnt gas before plosive mixture is introduced thereinto.

shown in the present dis is provided entirely around. in that portion which turnsthe new charge of ex-' By placing the In. use, the intaketo the explosion chain-I beris continued during-the length of time that it takes thecylinder 7 to'move in that partindicated between the lines a and b topass the openin 4 which communicates with the explosion c amber, the compression period Within the explosion chamber will continue during the length of time that the cylinder 7 requires to move that part of its circumference indicated between the lines and 0 topass the opening 4, the firing cycle will extend from indicated at a to the point at J, and irom this point indicated at cl to the point indicated at a the burnt gases will be permitted to exhaust from the. explosion chamber through the openings 3,4, and the passage 14 to prepare the explosion chamberfor the new charge which is to be admitted immediately upon'the completion of the exhaust action.

From the foregoing, it will be seen that I have provided a mechanism adapted to be attached around' a port formed through the cylinder of a gas engine to communicate with the explosion chamber thereof and. .to

form a common intake and exhaust port,

which mechanism is so arrangedthat communicationis established between said port and a gas-supply pipe connected with the mechanism at the proper" intake interval, the port is closed during the compression and firing interval, and the port is again opened to permit the exhaust subsequent to the firing cycle of the engine, further it will be seen that the mechanism is positive in its operation and that there is a gradual opening and closing of the port establishing communication with the explosion chamber on both the intake interval and the exhaust interval. a

WhileI hav herein shown and described one specific form of my invention, it will be understood that slight changes might be made in the form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not Wish to be limited thereto except for such limitations as the claims may import.
